Ion is generally regarded as one of Euripides' most attractive plays. A skilfully organised plot, charming characters, exciting situations and thought-provoking themes make it an excellent introduction to the study of Greek drama generally and of Euripides in particular. The introduction deals with Euripides' adaptation of the myth of Ion, his treatment of the theme of autochthony and his attitude to the seemingly licentious behavior of Apollo. There is also a discussion of the play's date, its structure, form and language. The commentary is designed to encourage students to read the play in a responsive way and pay attention to matters of form, language and dramatic technique.
